I Peter brings hope to those who suffer in 1:6-7 "In this you greatly rejoice, though now for a little while you may have had to suffer grief in all kinds of trials. These have come so that your faith - of greater worth than gold, which perishes even though refined by fire - may be proved genuine and may result in praise, glory and honor when Jesus Christ is revealed."
Peter tells believers that they should be 2:2 "Like newborn babies, crave pure spiritual milk, so that you may grow up in you salvation, now that you have tasted that the Lord is good." To do this he instructs Christians to abandon 2:1 "...malice and all deceit, hypocrisy, envy, and slander of every kind."
He further advises kindness and respect to all people, 2:15 "For it is God's will that by doing good you should silence the ignorant talk of foolish men. Live as free men, but do not use your freedom as a cover-up for evil; live as servants of God! Show proper respect to everyone: Love the brotherhood of believers fear God honor the King."
Peter charges Christians with a very important responsibility 3:15 "But in your hearts set apart Christ as Lord. Always be prepared to give an answer to everyone who asks you to give the reason for the hope you have. But do this with gentleness and respect..."
